"I named a 40-man provisional squad a fortnight ago because so many of the players had yet to play for their clubs," said Republic of Ireland boss McCarthy.

It means O'Hara is set to be available for Albion's EFL Trophy trip to Crewe Alexandra on September 3, when they will be missing Liam Boyce (Northern Ireland) and Everton loanee Nathan Broadhead (Wales under-21s).

O'Hara would also have been available for the League One game away to Sunderland, which was scheduled for September 7 - but that has now been postponed due to the number of international call-ups for the Black Cats.
